Trial Outcomes & Findings for Efficacy and Safety of MT-9938 for Treatment of Uremic Pruritus in Subjects With End-stage Renal Disease Receiving Hemodialysis (NCT NCT01660243)

NCT ID: NCT01660243

Last Updated: 2022-02-09

Results Overview

The subject indicated the number on the line from left (0:no itching) to right (10:worst itch I have ever experienced). Assessments was made twice daily using an electronic Patient Reported Outcomes (ePRO) device from the Screening Visit to the Follow-up Visit (Week 9). The 2 daily assessments was separated by 12 h, at approximately 8 am and at approximately 8 pm. Subjects selected the number that best described the worst itch during the day (assessed at approximately 8 pm) or during the night (assessed at approximately 8 am). The day or night score, whichever was greater, was used to calculate the weekly average score and changes from baseline (average over the Run-in Phase \[Days -7 to -1\]) score in weekly average at 2, 4 and 8 weeks as specified in the protocol are reported. Amount of change score of plus indicates worsening, and minus indicates improvement.

Participant Flow

Subjects who remained eligible entered the 1-week Run-in Phase. The NRS, VAS, and Itch Severity Score were averaged and formed the Baseline itch-intensity scores. After the Run-in, subjects who met additional inclusion criteria (having an NRS score for at least 5 days out of the 7 days and a mean worst NRS score ≥5) entered the Double-blind Treatment Phase (8 weeks) and were randomized to 1 of 4 study treatments.

PRIMARY outcome

Timeframe: 2 weeks, 4 weeks and 8 weeks

Population: ITT

The subject placed a single vertical mark on the line of a VAS corresponding to degree of itching intensity from left (no itching) to right (worst itch I have ever experienced). The VAS represents a 100 mm line. It consists of 101 selectable regions and the subject's score on the VAS will correspond to the region (0 to 100) selected on the line. Assessments was made twice daily using an ePRO device from the Screening Visit to the Follow-up Visit (Week 9). The 2 daily assessments was separated by 12 h, in the morning at approximately 8 am and in the night at approximately 8 pm. Subjects put a single vertical mark on the line to show the intensity of your worst itching during the day or during the night. The day or night score, whichever was greater, was used to calculate the weekly average score and changes from baseline in weekly average at 2, 4 and 8 weeks as specified in the protocol are reported. Amount of change score of plus indicates worsening, and minus indicates improvement.

PRIMARY outcome

Timeframe: 2 weeks, 4 weeks and 8 weeks

Population: ITT

The subject performed an assessment on day and nighttime symptoms of itch and effect of itch on sleep using a 5-point ordinal scale of itchiness (0 = none, 1 = mild, 2 = Moderate, 3=Severe, 4 = very severe). Assessments was made during each dialysis treatment (3x/week) and recorded on paper from the Screening Visit to the Follow-up Visit (Week 9). Change from Baseline (average over the Run-in Phase \[Days -7 to -1\]) in Weekly Averages of Itch Severity Score were assessed and score at 2, 4 and 8 weeks as specified in the protocol are reported. Amount of change score of plus indicates worsening, and minus indicates improvement.

PRIMARY outcome

Population: ITT

The Skindex-10 has a minimum possible score of 0 (itching not bothersome) and a maximum possible score of 60 (itching very bothersome). The Skindex-10 is a self-administered questionnaire used to evaluate the health-related QoL in UP. It is comprised of 10 questions, adopted for pruritus from the Skindex-16, a widely used instrument for a variety of skin disease. Subjects was asked to identify on paper at Baseline and Weeks 2, 4, and 8 (EOT) what has bothered them most during the past week by marking along a scale 0 to 6 boxes from "never bothered" to "always bothered. Change from Baseline (the Run-in Phase \[Days -7 to -1\]) were assessed. Amount of change score of plus indicates worsening, and minus indicates improvement.

PRIMARY outcome

Timeframe: 2 weeks, 4 weeks and 8 weeks

Population: ITT

The PGIC has a minimum possible score of 1 (very much improved) and a maximum possible score of 7 (very much worse). Subjects was asked to use a categorical scale with 7 categories to describe their global impression of change (PGIC) with study drug treatment. Subjects recorded their impression of change on paper at Weeks 2, 4, and 8 (EOT). Although the change from baseline (run-in phase \[Days -7 to -1\]) was specified as an outcome in this study, it was not calculated because the target enrollment was not met and no meaningful statistical analysis could be expected. Therefore, the mean value of patients at each point is shown instead.

Population: ITT

The 5-D-Itch scale has a minimum possible score of 5 (better) and a maximum possible score of 25 (worse). Subjects was asked to assess QoL by means of the 5D-Itch-Scale at Baseline, Weeks 2, 4, and 8 (EOT). The 5D-Itch Scale is a 5-item (duration, degree, direction, disability, and distribution) multidimensional measure of pruritus itch. Change from Baseline (the Run-in Phase \[Days -7 to -1\]) were assessed. Amount of change score of plus indicates worsening, and minus indicates improvement.

PRIMARY outcome

Timeframe: 2 weeks, 4 weeks and 8 weeks

Population: Not all rows could be analyzed with the overall number analyzed due to several reasons (e.g. patient discontinuation, missing data etc.), so some rows have different number of subjects analyzed.

Investigator and/or the designated medically qualified staff assessed the subject's excoriation at Baseline, and weekly thereafter, by completing the subject's answers to the following questions: Excoriation present? Yes/No If yes, please rate the severity: Mild/Moderate/Severe Although the change from baseline (run-in phase \[Days -7 to -1\]) was specified as an outcome in this study, it was not calculated because the target enrollment was not met and no meaningful statistical analysis could be expected.
